Precoding Matrix Configuration Method and Apparatus

4. The precoding matrix configuration method according to claim 1, wherein the M precoding matrices are obtained by repeating a precoding matrix group, the first configuration information is used to configure one or more offsets, a first precoding matrix in the precoding matrix group, and a quantity of repetitions of the precoding matrix group, and each of the one or more offsets is an offset of a number of a precoding matrix in the precoding matrix group relative to a number of another precoding matrix in the precoding matrix group.

10. The precoding matrix configuration apparatus according to claim 7, wherein the M precoding matrices are obtained by repeating a precoding matrix group, the first configuration information is used to configure one or more offsets, a first precoding matrix in the precoding matrix group, and a quantity of repetitions of the precoding matrix group, and each of the one or more offsets is an offset of a number of a precoding matrix in the precoding matrix group relative to a number of another precoding matrix in the precoding matrix group.

13. The precoding matrix configuration apparatus according to claim 7, wherein the apparatus is a terminal device, a chip or a chip system.

17. The non-transitory computer-readable storage medium according to claim 14, wherein the M precoding matrices are obtained by repeating a precoding matrix group, the first configuration information is used to configure one or more offsets, a first precoding matrix in the precoding matrix group, and a quantity of repetitions of the precoding matrix group, and each of the one or more offsets is an offset of a number of a precoding matrix in the precoding matrix group relative to a number of another precoding matrix in the precoding matrix group.
